The
Stip-scan
is the first generation of a new type of spectroscopic
sensor that measures wastewater using a light spectrum from
190 to 720 nm. In addition a new patented settlement phase
can be used to provide an on-line measurment of Total
Solids and SVI
(Sludge Volume Index).
Recent
developments in spectral measurement presents possibilities
for measuring in-situ a wide range of parameters simultaneously
such as NO3, SAC(UV 254), COD, and TOC. However interfering
effects of turbidity, colour and "overlapping"
absorbtion spectra must be taken into account for accurate
and reliable measurement, especially in a changing wastewater
matrix. The Stip-scan
solids settlement phase
enables such potential interferences to be accomodated and
results in greater precision and confidence with measured
results.
